Optlime, A Bioecenomic Model Of Soil Acidity Management In Agricultural Systems, Chris Gazey

All other publications

Optlime is a model that represents the essential biological, physical and economic factors related to soil acidity management in Western Australia. The model allows users to define site and soil characteristics for an acidic scenario and then simultaneously assess likely outcomes for 2 different lime sources and application strategies. With and without liming scenarios are examined over a 20 year simulation so as to capture the long-term impacts of soil acidity management. Output provided allows you to examine the likely effect of liming on pH, exchangeable aluminium, yields, and profits. An investment appraisal is provided to show you how liming …

This guide summarises performance characteristics of commercially available wheats and some pre-commercial lines. These lines have undergone testing in the National Variety Testing Project (NVT), Department of Agriculture and Food, Western Australia (DAFWA) wide-scale crop variety testing (CVT) and/or variety specific agronomy projects. This information includes variety summaries (Table 1), agronomic, disease and herbicide tolerance characteristics (Tables 2 to 4), medium- to long-term yield performance by wheat grade and Agzone (Tables 5 and 6). A review of regional performance in 2007 is followed by a comprehensive summary of 2007 variety time of sowing experiments (Tables 7 to 14) and flowering …
